SAS H-FASTENER.

SPECIFICATION forming part of Letters Patent No. 264,539, dated September 19, 1882.

Application filed August 7, 1882. (No model.)

To all whom it may concern:

Be it known that I, ELEAZER KEMPSHALL, of New Britain, in the county of Hartford and State of Connecticut, have, invented certain new and useful Improvements in Sash-Fasteners, of which the following is a specification.

My invention relates to sash-fasteners in which a short cylindrical zinc case covers a part of the bolt near one end, and its surrounding spring, while atthe part of the bolt which projects from the inner or small end of the case,

is of full size for alength sufficient to form a bearingin asuitable bushingplaced in thestile; and the objects of my invention are tomake the fastener more eflicient, tasty, and durable by taking the wearfrom theedgeofthezi-nccase at the small end'and transferringit to a bushing placedin the stile, also by shortening the case so as to make the inner end of the bolt of larger size, and, further, by adapting the parts to be so placed in the stile that no strain s hall even come upon the reduced and weakest portion of the bolt. I attain these objects by the simple construction illustrated inthe accom-' panying drawings, in which Figure 1 is a side elevation of my sash-fastener; and Fig, 2 is a vertical section of the same, partly in elevation, and showing-also portion of the sash-stile.

With certain exceptions, hereinafter specified, the bolt A, spring a, and case B are the same as those now in common use-that is to say, the bolt has a projecting handle, b,a projecting end, 0, to engage the \vindow-jamb, a reduced portion around which the spring is coiled, and a surroundingthinmetalcase, generally zinc, having a rolled flange, d, projecting from its large or outer end and an in ward: ly-turned flange, e, at its inner-end. The case of my sash-fastener differs from the prior con-;

ing the reduced portion farther from the handle b and leaving a straight part, f, between the case and the handle of the same diameter as the outer end, 0-, of the bolt, whereby itis adapted to form a bearing-surface at a point without the casing. In connection with this change of structure, 1 form a small bushing, 0, whose inner diameter is of a proper size to re ceive and guide the part f of the bolt, and whose outer diameter is substantially the same as that, of the case. A plain straight hole is bored through the stile, D, and the case and bolt driven inat one end and the bushing G at the other end, as shown in Fig. 2. The bushing finishes the hole in the sash neatly,

and, even in a narrow stile,'the inner end of the case is not exposed to view. ln'lit'ting upon the handle the wear and strain comes upon the durable bushing, and not upon the thin and fragile edge of the metal at theinner end of the case. The straight partfis never wholly withdrawn from the bushing, and consequently no lifting strain can ever be brought to hear Witnesses JAMES SHEPARD,
